4 Product & Execution III Execution 2.4 ACCESSORIES AND INSTALLATION COMPONENTS A. Always use Nichiha accessories for complete and proper installation, whether or not specifically shown on installation drawings. B. Additional accessories for installation and designer aesthetics are available. Consult catalog or contact Nichiha USA Inc., for further details. 3.1 HANDLING A. Panels must be stored flat and kept dry before installation. A waterproof cover over panel s and accessories should be used at all times prior to installation. B. If panels are exposed to water or water vapor prior to installation, allow to completely dry before installing. Failure to do so may result in shrinkage at ship lap joints, and such action may void warranty. C. Nichiha panels MUST be carried on edge. Do not carry or lift panels flat. Improper handling may cause cracking or panel damage. Nichiha is not responsible for damage caused by improper handling. D. Direct contact between the panels and the ground should be avoided at all times. It is necessary to keep panels clean during installation process. 3.2 JOB CONDITIONS A. Nichiha fiber cement panels can be installed over bracing wood, steel studs and sheathing including; ply wood, OSB, plastic foam or fiberboard sheathing. Nichiha fiber cement panels can also be installed over Structural Insulated Panels (SIP s), Concrete Masonry Units (CMU s), and Concrete Block Structures (CBS s) with furring strips, and Pre-Engineered Metal Construction. B. Allowable stud spacing: See manufacturer s installation instructions for details. C A weather resistant barrier is required when installing Nichiha fiber cement panels. Use an approved weather resistant barrier [WRB] as defined by the 2007 IRC. Refer to local building codes. Nichiha is not responsible for water infiltration. D. Appropriate metal flashing should be used to prevent moisture penetration around all doors, windows, wall bottoms, material transitions and penetrations. Please refer to local building codes for best pract 3.3 SURFACE CONDITIONS A. Examine site to ensure substrate conditions are within specification for proper installation. B. Do not begin installation until unacceptable conditions have been corrected. 3.4 CUTTING A. Always cut Nichiha Block panels outside or in a well ventilated area. Do not cut the products in an enclosed area. B. Always wear safety glasses and NIOSH/OSHA approved respirator, whenever cutting, drilling, sawing, sanding or abrading the products. Refer to manufacturer MSDS for more information. C. Use a dust-reducing circular saw with a diamond-tipped or carbide-tipped blade, for general cuttings. Recommended circular saw: Makita 7-1/4" Circular Saw with Dust Collector (#5057KB). Recommended blade: Tenryu Board-Pro Plus PCD Blade (#BP-18505). Shears (electric or pneumatic) or jig saw can be used for complicated cuttings, such as service openings, curves, radii and scrollwork.

5 Execution III Execution (continued) D. Silica Dust Warning: Nichiha products contain crystalline silica (a.k.a. sand, silicon dioxide), which is a common Earth s naturally occurring mineral. Inhalation of crystalline silica into the lungs and repeated exposure to silica can cause health disorders, such as silicosis, lung cancer, or potentially death depending on various factors. To be conservative, Nichiha requires that, whenever drilling, cutting, sawing, sanding or abrading the product, users must observe the following safety practices: 1) Use best work practices (proper cutting blade) to reduce airborne dust concentrations. 2) Use a fiber cement circular saw with a dust collector for cutting (e.g., Makita 5057KB). The dust collector must be connected to a HEPA vacuum. 3) Do not use compressed air for cleaning dust. 4) Work outdoors where feasible; otherwise, use mechanical ventilation. 5) Everyone handling Nichiha products must wear safety glasses and properly fitted respirators prior to handling Nichiha products. Nichiha requires that users wear a NIOSH/OSHA approved respirator with a rating of N100, O100, P100, or R100 in accordance with applicable government regulations and manufacturer instructions. All employers must comply with the OSHA PEL and ACGIH TLV-TWA. 6) Warn others in area. These requirements are designed to help minimize exposure to crystalline silica. We also require that you read all instructions and warnings (including the MSDS) prior to using Nichiha product. For further information or questions, please consult the MSDS or your employer. The MSDS for Nichiha products are available at Nichiha.com at your local Nichiha dealer or through Nichiha directly at MSDS s are also available at the back of this manual. FAILURE TO ADHERE TO OUR WARNINGS, MSDS, AND OTHER INSTRUCTIONS MAY LEAD TO SERIOUS PERSONAL INJURY OR DEATH. 3.5 FASTENING A. Corrosion resistant fasteners, such as hot-dipped galvanized nails and screws that are appropriate to local building codes and practices must be used. Stainless Steel fasteners are highly recommended in highhumidity and high-moisture regions. Nichiha is not liable for corrosion resistance of fasteners. Do not use aluminum fasteners, staples, clipped head nails or fasteners that are not rated or designed for intended use. See manufacturer s detailed instructions for appropriate fasteners for construction method used. 3.6 INSTALLATION A. General: Install products in accordance with the latest installation guidelines of the manufacturer and all applicable building codes and other laws, rules, regulations and ordinances. Review all manufacturer installation, maintenance instructions and other applicable documents before installation. 1. Nichiha panels can be installed on many types of construction methods, review individual installation details for specifics for each type of construction method. Nichiha fiber cement panels can be installed over Wood and Metal Stud Construction, Structural Insulated Panels (SIP s), Concrete Masonry Units (CMU s), Concrete Block Structures (CBS s), and Pre-Engineered Metal Construction. Install Nichiha panels in accordance with the manufacturer s detailed installation instruction for the construction method used. 2. Please consult with your local dealer or Nichiha Technical Department before installing any Nichiha fiber cement product on a building 45 feet or higher or three [3] stories or higher. Special installation conditions may be required. 3.7 FINISHING AND MAINTENANCE A. Review brick, stone and block Maintenance, Repair and Cleaning Guidelines for detailed care instructions.
